🖍️ Why you’ll love these crayons

These crayons are a great way to repurpose broken or old crayons. I always save crayons from restaurants to melt down. This is a great project for Earth Day too since it re-uses items that would otherwise be thrown away.

You can make so many fun crayons for friends and family during holidays too. These are also awesome for classroom party favors.

📋 Supplies needed

supplies needed to melt crayons in the oven
  • Broken crayons: I’ve heard that Crayola brand crayons work best when remaking crayons, but I used a variety of whatever was in the bottom of our arts and crafts supply bucket with no problem.
  • Silicone mold of your choice: I used a heart shaped one.
  • Aluminum foil: Or you can also use parchment paper (not wax paper). This will keep your baking sheet clean.
  • Baking sheet: To keep the mold even and avoids spills when pulling it out of the oven.

⏲️ How to melt the crayons in silicone molds

Printable instructions are below.

Begin by soaking your crayons in a bowl of water (image 1). This will make it easy to peel the wrappers off. You can also use an exacto knife or razor (adults only). I had my kids help so soaking and not using anything sharp was easier for us.

Dry your crayons off on a towel (image 2). Make sure there’s no excess water on them. Break your crayons and place them in the mold. Cover a baking sheet with aluminum foil and place your silicone mold on it. (image 3).

I used similar colors in each individual mold for my crayons but you can use whatever colors you want. Mixing colors is a fun option. I did try to avoid using black and white crayons with other colors.

Bake your crayon pieces at 350 degrees for 8 to 10 minutes. You’ll want to check and make sure they are melted completely since your oven or mold might require more or less time.

Next, let them cool for 1 to 2 hours and then carefully remove them.

⭐ What mold to use

I used a silicone heart mold from Amazon.

📖 Tips

  • Line your baking sheet with parchment paper (not wax) or aluminum foil to prevent any spillage.
  • Wait until the crayons are fully cooled to remove them or they will break.
  • White and black are not good colors to use in molds. They don’t mix very well.

💬 Variations

green and blue heart shaped crayon
  • Use holiday colors like green and blue for Earth day, black and orange for Halloween, red and green for Christmas, or pink and red for Valentine’s Day.
  • Glitter crayons are also super fun for this project.
